Question

For the following statement, write T for True and F for false
The mass of an electron is about 1/2000 times that of a proton.

Answer 1

Hint: Electrons are much smaller than protons or neutrons. If an electron were the mass of a penny, a proton or a neutron would have the mass of a large bowling ball!

Complete step by step solution:
 As we know that Electron are extremely small and proton is an independent subatomic particle of an atom
So,The mass of an electron is only about 1/2000 the mass of a proton or neutron, so electrons contribute virtually nothing to the total mass of an atom. Electrons have an electric charge of −1, which is equal but opposite to the charge of a proton, which is +1.

Additional information: Electrons are one of three main types of particles that make up atoms. The other two types are protons and neutrons. Unlike protons and neutrons, which consist of smaller, simpler particles, electrons are fundamental particles that do not consist of smaller particles. They are a type of fundamental particles called leptons. All leptons have an electric charge of −1−1 or 00.
 A proton is one of three main particles that make up the atom. The other two particles are the neutron and electron. Protons are found in the nucleus of the atom.

Note: Mass of electron (in Kg) = 5.54×10^-4, Mass of proton=1.67×10^-27
 Which shows that electrons are much heavier than protons.
